What the Sentence Splitter does
Sentence Splitter: processes Pieces and Output (one per line) from Text, Split into and Delimiter. Example: split into Sentences, delimiter , and number the pieces No gives pieces 4.
Feed it Text, Split into, Delimiter and Number the pieces; it hands back Pieces and Output (one per line). Change any input and the output follows immediately.
Text pasted from another program usually arrives with formatting nobody wants. That is usually what brings anyone reformatting pasted text here.
This runs client-side, which means we never receive what you enter and could not retrieve it if asked.
Below the tool you will find the field reference, the method, and an example computed from the values it opens with.
What do the Sentence Splitter fields mean?
The Sentence Splitter uses 4 inputs. Because the form arrives filled, the first useful result costs you zero typing.
| Field | What to enter | Default |
|---|---|---|
| Text | paste or type any amount of text | Dr. Smith arrived at 9 a.m. He was late! Was the U.S. team ready? "Yes," she said. Then everyone left... |
| Split into | choose from Sentences, Words, Characters, Paragraphs or Custom delimiter | Sentences |
| Delimiter | optional | , |
| Number the pieces | choose from Yes or No | No |
How does the Sentence Splitter work?
Each output is derived from the inputs above in a single pass; there is no hidden state carried between runs, so the same inputs always give the same result.
Bad input produces an error, never a confident-looking wrong answer.
Worked example
These are the values the Sentence Splitter loads by default, and the result it produces from them. Open the tool above and you will find precisely these figures already in place.
| Text | Dr. Smith arrived at 9 a.m. He was late! Was the U.S. tea… |
|---|---|
| Split into | Sentences |
| Delimiter | , |
| Number the pieces | No |
| Pieces | 4 |
|---|---|
| Output (one per line) | Dr. Smith arrived at 9 a.m. He was late! Was the U.S. team ready? "Yes," she said. Then everyone left... |

What this tool does not do

- No allowance is made for local rules, regional variations or house conventions.
